P or Cal deficiency, or overfed. Not sure

Yes Logan your right with the benies! And not wrong at all with the expense side of things. A bit dodgey going in to the supermarket and buying 15, 10 litre waters haha. But so worth it in the end imo. I bought an ro system a while back but little did I know I should of got one with a pump! Once it uses up its 5 litres it trickles into the tank and seems to take all day to fill again...... I'm in the process of buying a half decent one. Just gotta research a little more. Would you have any ideas on a good ro system with pump Logan?

Hahahaha I feel your pain I did the same thing on my first hydro run, got lots of dirty looks! I actually have the kind that you're talking about and my god, is it dreadful! I spend 1 and 2 days building up water for a res change on a few plants! If I could go back and buy a different one, I would probably get this one here: https://www.amazon.com/HiKiNS-Reverse-Tankless-Residential-Filtration/dp/B07L3N5GLF/ref=sr_1_fkmrnull_9_sspa?keywords=Ninja+reverse+osmosis+water&qid=1551641126&s=gateway&sr=8-9-fkmrnull-spons&psc=1
But I'd like to note that I've not actually tried it, just the one that I would love to buy in the future. As you see, no tank or anything, just outputs it directly from the filter to the spout. It's not the cheapest in the world, but me and you have both already found out what kind you get for cheap lol.

Haha. Worst part is ive been doing dwc for about 3 years!! I usually mix the distilled water 50/50 make it go further and drops my ppm to 200 lol. (Unless plants are suffering or when rooted clone goes into dwc with some root beneficials) worst part is that ro system is a little cheaper than what i played for mine lol. Not sure what the flow would be like on the one you just showed me? but you can buy them exactly like that but with a small pump for more pressure.... like you said, doesnt take 24 hours to do a res change lol.

It is alleged to has a 600+ Gallon Per Day output, but I'm sure that measurment was taken in their favor. And jesus you've had a tough 3 years then I bet lol.

Ohh wow. Even if its quarter that, ill be a happy man! Stuff it, Think I might just buy it now haha. And yes I have haha. But still sooo worth it!! Also our supermarket here delivers to the door on orders over a certain amount so i get them to my door sometimes lol. Had a couple of delivery drivers ask me what all the waters for? I just say i work in a fernice, work pays me back for the water for me and the boys haha.
